Numerical Investigation of the Lateral Movement Influence on the Levitation Force of the Bulk HTS Based on a 3-D Model

On the basis of a 3-D model of the high- superconducting maglev, the characteristics of the levitation force (LF) of a bulk high-T_c superconductor (HTS) under continuous lateral movement was numerically investigated. The Functional rule of the influencing factors, such as field-cooling height (FCH), levitation height (LH), maximum lateral displacement (MLD), and material property, was demonstrated. The results indicate that, for the case with a shorter MLD, and better material property, the LF decay due to lateral movement is more remarkable. Finally, the Pre-Loading, i.e., make the bulk HTS trap more fluxes before working, was also simulated and its validation to reduce the LF decay is confirmed.
